droning is your exhaust NOT test pipes. and rattling is cheap resonated test pipes which say remove rasp and drone. which they dont do either. just test pipes that a pipe nothing more is the way to go. ive been in the VQ area for a very long time. built them up and torn them down. 650whp+ i know it all...
